The Need for Different Classes of Macroeconomic Models (DSGEs). Blanchard

This is is my third piece on dynamic stochastic general equilibrium models (DSGEs). 

 The first, a PIIE Policy Brief, was triggered by a project, led by David Vines, to assess how DSGEs had performed during the financial crisis (namely, badly) and how they could be improved. 

 That brief went nearly viral (by the standards of blogs on DSGEs ☺).

Niall Ferguson: The AI Boom Is a House of Cards, Tyler Cowen: Not so fast

AI is driving markets and GDP growth—but the underlying financing resembles the 19th-century railroad industry, which had its own share of crashes. Financial history can help us here. If you’re unsure if there’s an AI bubble, refer to the historian Charles Kindleberger’s five-stage model: Displacement: Some change in economic circumstances creates new and profitable opportunities for certain companies. Euphoria or overtrading: A feedback process sets in whereby rising expected profits lead to rapid growth in share prices. Mania or bubble: The prospect of easy capital gains attracts first-time investors and swindlers eager to defraud them. Distress: The insiders discern that expected profits cannot possibly justify the now-exorbitant price of the shares and begin to take profits by selling. Revulsion or discredit: As share prices fall, the outsiders stampede for the exits, causing the bubble to burst altogether. We are currently at stage 3.

Cognitive blind spots

Bild
Cognitive blind spots are undermining our ability to see the world as it is, rather than as we would like it to be. At the start of the 21st century, western elites generally assumed that globalisation, democracy and the free market were self-evidently good, and would keep spreading, creating peace. N o longer.  FIS, Swiss Federal Intelligence Service, has published a manual about cognitive blind spots. 18 different cognitive biases that hamper our thinking, such as “group think” (adhering to the cosy assumptions of our tribe), “anchoring” (relying exclusively on whatever information we see first, say on social media),  “confirmation bias” (only seeing data that reinforces pre-existing views),  “mirror imaging” (assuming others think like us),  “absence of evidence” bias (failing to think about the data we lack)  and “survivorship bias” (judging data only with success stories, not failures).
